“Laval” is an archetype of FIRE monsters, whose effects mainly focus on setting up the Graveyard and then taking advantage of it. Some “Laval” monsters, like Laval Volcano Handmaiden, are able to send cards of their own archetype to the Graveyard, others, like Laval Stennon, can then use those cards to activate their effects.
Interestingly enough, after the release of Absolute Inferno, we are only missing two “Laval” monsters to complete the archetype: Laval Judgment Lord and Laval Magma Cannoneer, both of which are able to deal up to 1000 effect damage per turn via their effects. Anyway, now that we have Molten Conduction Field, it is definitely a lot easier to set up the Graveyard and, thanks to the Tuners introduced in the new Main BOX, the deck has access to a decent Extra Deck, which is also quite nice.
Use Molten Conduction Field and Needlebug Nest to set up your Graveyard for Dustflame Blast. If you have at least another “Laval” monster in your Graveyard when Laval Volcano Handmaiden is sent there, it will allow you to send a “Laval” monster from your Deck to the Graveyard.
Since Molten Conduction Field and Needlebug Nest send all cards to the Graveyard simultaneously, it will be quite easy to activate Handmaiden’s effect as long as you don’t send it to the Graveyard on Chain Link 2 or higher or to activate a card like Enemy Controller or Hallowed Life Barrier.
Handmaiden’s effect will trigger even if it’s destroyed by battle or card effect, but you still need at least a “Laval” monster in your Graveyard other than “Laval Volcano Handmaiden” for that to happen. You could technically send all copies of Handmaiden to the Graveyard at once, but it’s still advised to keep at least one in your Deck to activate Molten Conduction Field without having to send Laval Cannon to the Graveyard.
If you have 3 or more "Laval" monsters with different names in your Graveyard, you can banish Laval Lakeside Lady and another "Laval" monster from your Graveyard to target 1 Set card your opponent controls and destroy that target. There are a few issues with this effect:
If you target a Set card and your opponent flips it face-up in response, the card does NOT get destroyed because it’s not a suitable target anymore;
Aggressive decks such as Koa'ki Meiru rarely have anything they want to Set aside from a Winged Kuriboh. You can only target cards on your opponent’s side of the field, so you are not always going to be able to activate this effect.
Setting that aside, this effect can be used to enable Laval Cannon’s effect and Synchro Summon and it’s not that bad when you’re facing off against Control and Stall decks, which do run a lot of back row. Getting three “Laval” monsters with different names into the Graveyard is really not an issue thanks to Laval Volcano Handmaiden.
When it’s Normal or Flip Summoned, Laval Cannon allows you to Special Summon one of your banished “Laval” monsters. Special Summon one of your banished Tuners via Laval Cannon’s effect and then use them to Synchro Summon.
Dustflame Blast is a really powerful Trap Card that, with enough setup, could even end up wiping your opponent’s entire board by itself. In order to activate Dustflame Blast, you have to banish all “Laval” monsters from your Graveyard, which synergizes perfectly with Laval Cannon’s effect.
Bouncing cards back into the opponent’s hand is a surprising efficient form of removal: big threats such as Koa'ki Meiru Maximus and Ancient Gear Reactor Dragon will be difficult to bring back right away. You can use the monsters you used to Summon Lavalval Dragon to activate its effect.
Whenever you don’t need to bounce a card on the opponent’s side of the field, you can go into Armades and take a slower approach. Armades is a Level 5 Synchro that is able to prevent your opponent from activating cards or effects until the end of the Damage Step if it attacks or is attacked; your opponent will not be able to use Sphere Kuriboh, Drowning Mirror Force, Widespread Ruin and Wall of Disruption, but you will still have access to your own Spell & Trap Cards.
You can declare an attack with Armades and then activate Paleozoic Canadia or Enemy Controller: your opponent will not be able to negate their effects or respond to their activation, which relevant against Koa'ki Meiru and many other decks.
Laval Stennon is your highest ATK monsters, which is kind of underwhelming since it needs Beatdown to reach 3000 ATK. This Level 7 Synchro can negate the effect of any card that targets it by simply banishing a “Laval” monster from your Graveyard. As long as your opponent is not able to get over Stennon by battle, it will be quite difficult to deal with this monster.
Reinforcement Can be used each time your Life Points decrease by 1800. Return 1 card from your hand to your Deck and draw a random Warrior-Type monster.
This Skill allows Laval Stennon to reach exactly 3000 ATK by itself, which is enough to tie with Koa'ki Meiru Maximus and Ancient Gear Reactor Dragon.
The deck struggles against anything that is above 2700 ATK if Dustflame Blast, Enemy Controller and Lavalval Dragon are not available. You could technically combine Paleozoic Canadia and Laval Lakeside Lady to get rid of these monsters, but it would be a really convoluted way of doing so.
Yes locals r the f2p ding of games deck. Only requires 1xUR and 4xSR which u can get by just pulling the box. Everything else is rare and common.
(My kog deck had 1x Laval dragon and 2x lake lady and conduction field)
Every time I play against this deck, the guy I'm fighting takes 7 turns to do anything, and then decides summoning Laval Dragoon while I have three traps on field is a good idea. Not sure if people understand the deck yet, but im hoping to see it in full glorious action someday.
